Physical properties
Hardness of 6.5-7 on Mohs scale, opaque luster, various earth tones, trigonal crystal system with conchoidal fracture.
Formation & geological history
Forms from silica-rich fluids precipitating in sedimentary environments or hydrothermal veins over millions of years.
Uses & applications
Used widely in ornamental carvings, cabochons, jewelry, and polished display specimens.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and decorative weaponry due to its durability and rich coloration.
Field identification & locations
Identified by its opaque nature, waxy luster, and lack of cleavage; found globally in riverbeds and mountainous regions.
